The remote NewStart CGSL host, running version MAIN 7.02, has httpd packages installed that are affected by multiple vulnerabilities:

  - Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure,     SSRF or local script execution via backend applications whose response headers are malicious or     exploitable. Users are recommended to upgrade to version 2.4.60, which fixes this issue. (CVE-2024-38476)

  - Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server:
    through 2.4.57. (CVE-2023-31122)

  - An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of     that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the     server, similar to the well known slow loris attack pattern. This has been fixed in version 2.4.58, so     that such connection are terminated properly after the configured connection timeout. This issue affects     Apache HTTP Server: from 2.4.55 through 2.4.57. Users are recommended to upgrade to version 2.4.58, which     fixes the issue. (CVE-2023-43622)

  - When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory     resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A     client could send new requests and resets, keeping the connection busy and open and causing the memory     footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run     out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid     Reset Exploit) with their own test client. During normal HTTP/2 use, the probability to hit this bug is     very low. The kept memory would not become noticeable before the connection closes or times out. Users are     recommended to upgrade to version 2.4.58, which fixes the issue. (CVE-2023-45802)

  - Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference,     leading to a crash of the server process, degrading performance. (CVE-2024-36387)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-689 advisory.

    Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference,     leading to a crash of the server process, degrading performance. (CVE-2024-36387)

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:3452 advisory.

    Red Hat JBoss Core Services is a set of supplementary software for Red Hat JBoss middleware products. This     software, such as Apache HTTP Server, is common to multiple JBoss middleware products and packaged under     Red Hat JBoss Core Services, to allow for faster distribution of updates and for a more consistent update     experience.

    This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.62 serves as a replacement for Red Hat     JBoss Core Services Apache HTTP Server 2.4.57 Service Pack 6, and includes bug fixes and enhancements,     which are documented in the Release Notes linked to in the References section.

    Security Fix(es):

    * openssl: SSL_select_next_proto buffer overread (CVE-2024-5535)
    * mod_http2: DoS by null pointer in websocket over HTTP/2 (CVE-2024-36387)

The version of httpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-36387 advisory.

  - Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference,     leading to a crash of the server process, degrading performance. (CVE-2024-36387)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 9 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2024-8680 advisory.

    [2.0.26-2.1]
    - Resolves: RHEL-45803 - mod_http2: DoS by null pointer in websocket       over HTTP/2 (CVE-2024-36387)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to its self-reported version, the Tenable Security Center running on the remote host is 6.2.1, 6.3.0 or 6.4.0.
It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-13 advisory.

  - Security Center leverages third-party software to help provide underlying functionality. Several of the     third-party components (Apache, libcurl) were found to contain vulnerabilities, and updated versions have     been made available by the providers.Out of caution and in line with best practice, Tenable has opted to     upgrade these components to address the potential impact of the issues. Security Center Patch SC-202408.1     updates Apache to version 2.4.62 and libcurl to version 8.8.0 to address the identified vulnerabilities.
    Tenable has released Security Center Patch SC-202408.1 to address these issues. The installation files can     be obtained from the Tenable Downloads Portal: https://www.tenable.com/downloads/security-center     (CVE-2024-2004, CVE-2024-2379, CVE-2024-2398, CVE-2024-2466, CVE-2024-36387, CVE-2024-38472,     CVE-2024-38473, CVE-2024-38474, CVE-2024-38475, CVE-2024-38476, CVE-2024-38477, CVE-2024-39573,     CVE-2024-39884, CVE-2024-40725, CVE-2024-40898, CVE-2024-6197, CVE-2024-6874)

遠端主機上安裝的 Apache httpd 版本早於 2.4.60。因此，會受到 2.4.60 公告中所提及的多個弱點影響。

  - 透過 HTTP/2 連線提供 WebSocket 通訊協定升級服務可導致 Null 指標解除參照，進而造成伺服器處理程序損毀，效能降低。(CVE-2024-36387)

  - Windows 上 Apache HTTP Server 中的 SSRF 可能允許透過 SSRF 和惡意要求或內容，將 NTML 雜湊洩漏給惡意伺服器，建議使用者升級至 2.4.60 版，以修正此問題。注意：存取 UNC 路徑的現有組態必須將新的指示詞 UNCList 設定為在要求處理期間允許存取。(CVE-2024-38472)

  - 在 Apache HTTP Server 2.4.59 和更舊版本中，mod_proxy 中存在編碼問題。此弱點可將具有錯誤編碼的要求 URL 傳送至後端服務，進而可能透過特製要求繞過驗證。建議使用者升級至已修正此問題 2.4.60 版。(CVE-2024-38473)

  - 在 Apache HTTP Server 2.4.59 和更舊版本中，mod_rewrite 中存在替換編碼問題。此弱點可讓攻擊者在設定允許的目錄中執行指令碼，但這些目錄無法直接透過任何 URL 或來源指令碼泄露方式存取，這些指令碼原本僅設計為以 CGI 方式執行。建議使用者升級至已修正此問題 2.4.60 版。除非指定重寫標記 UnsafeAllow3F，否則以不安全的方式擷取和替代的某些 RewriteRules 現在會失敗。(CVE-2024-38474)

  - 在 Apache HTTP Server 2.4.59 和更舊版本中，mod_rewrite 中存在輸出不當逸出問題。此弱點會讓攻擊者將 URL 對應至允許伺服器提供服務但任何 URL 無法刻意/直接存取的檔案系統位置，進而導致程式碼執行或來源程式碼洩漏。
    伺服器內容中使用反向參照或變數做為第一個取代區段的取代作業會受到影響。部分不安全的 RewiteRules 會因此變更而損毀，且攻擊者可使用重寫標記 UnsafePrefixStat 來選擇在確保適當限制取代作業後重新加入。
    (CVE-2024-38475)

  - Apache HTTP Server 2.4.59 和更舊版本的核心容易受到資訊洩漏、SSRF 或本機指令碼執行弱點的影響，攻擊者可透過具有惡意或可遭惡意利用的回應標頭的後端應用程式發動攻擊。建議使用者升級至已修正此問題 2.4.60 版。(CVE-2024-38476)

  - 在 Apache HTTP Server 2.4.59 和更舊版本中，mod_proxy 中存在 NULL 指標解除參照問題。此弱點可讓攻擊者透過惡意要求造成伺服器當機。建議使用者升級至已修正此問題 2.4.60 版。(CVE-2024-38477)

  - 在 Apache HTTP Server 2.4.59 和更舊版本中，mod_rewrite 中存在潛在 SSRF 問題。此弱點可讓攻擊者造成不安全的 RewriteRules，意外將 URL 設定為由 mod_proxy 處理。建議使用者升級至已修正此問題 2.4.60 版。(CVE-2024-39573)
